Adopting a methodology similar to Bali, Peng, Shen and Tang (2014), this essay investigates whether stock-level liquidity shocks predict future returns on the Swedish stock market. Liquidity is measured by the relative bid-ask spread. Portfolios with stocks that experienced positive liquidity shocks yield higher returns than portfolios with stocks that experienced negative liquidity shocks. The me
Use of stem cells from fat tissue for clinical application Stem cells isolated from fat tissue (Adipose Stem Cells, ASC) are desired therapeutic agents due to their good accessibility, high yield, ease of isolation, and their growth and differentiation capabilities. Under long-term in vitro culturing, cells lose their capabilities to grow and divide, and acquire an aging (senescent) morphology. S
This thesis applies a model for optimal top taxation rate on all Scandinavian countries. The starting point is a theory by Saez, Piketty and Stantcheva limiting the possible change in behavior of taxpayers into three channels; labor supply, tax avoidance and compensation bargaining. I show that optimal top taxation rate depends on these three key elasticities and how they affect the tax system. Th
Habitatkonnektivitet och förekomsten av gräsmarksfjärilar Dagens gräsmarker har ofta reducerats till små, geografiskt isolerade fragment omgivna och åtskilda av stora arealer med planterad skog eller åker. För gräsmarkslevande fjärilar utgör långa avstånd mellan livsmiljöerna ett stort hot då det innebär kraftigt försämrade spridningsmöjligheter. I den här studien har graden av habitatkonnektiviThe biologically important grasslands of today have due to last century’s major changes in land use often been reduced to small, geographically isolated fragments. The low level of habitat connectivity in fragmented landscapes, prevents dispersal of organisms and is considered to be a great threat to biodiversity. In this study the impact of connectivity on the abundance of 6 species of grassland
This study has investigated the adaptation ability among Swedish public institutions with the intention of contributing with an understanding of the governmental and institutional approach on how they are supposed to manage potential larger-scale relocation due to climate change in the not so far reaching future. My specific research objective was to study the case of adaptation ability among ins
This case study of the effectiveness of the usage of Japanese role language uses character portrayals from performances by the theatre company Takarazuka Revue to investigate how native Japanese speakers perceive characters solely based upon lexical or grammatical cues in spoken language. With a foundation in Satoshi Kinsui’s description of role language and Christopher Vogler’s character archetyp
Climate governance is diversifying as the traditional multilateral approach is complemented by more autonomous and experimental reactions. The aim of this thesis is to enquire into this new kind of climate governance. Through a comparative case study of two urban climate change experiments in Denmark, the thesis first explores mechanisms that aid and hinder the achievement of experiment objectives
Over the last decade, financial disclosure and its impact on equity markets has increasingly become an area of interest. Firms suffering from poor operating performance have been shown to disclose bias earnings estimates as a means of evading negative market reactions. In this thesis, we attempt to discern whether managers purposefully bias their earnings estimates in periods of credit quality det
This paper investigates whether countries can use tax-based forms of capital controls to affect the share of foreign direct investment (FDI) relative to debt. Doing so might enable a country to influence capital-recipient countries’ foreign capital towards FDI and away from debt. The empirical model and dependent, explanatory, and control variables have been drawn from existing literature and have
This bachelor thesis studies fashion photographs where drag queens are participating as models. It was aimed to explore how their function in the fashion context can be seen. Three cases from 2016, all from a North American context are used for the study. “Caged Heat” from Interview Magazine no. 3, 2016 where Violet Chachki can be seen as one of the models. “Walk in the Wild Side” from ODDA Magazi
3D-cellodling - ett steg närmare verkligen Den traditionella odlingen av celler sker i Petriskålar/flaskor. Detta system har varit och är fortfarande ett bra verktyg för att få en riktlinje och förstå hur celler, däribland även cancer celler, svarar på t.ex. behandlingar av olika substanser. Begränsningen med detta system är att cellerna växer i 2D, d.v.s. bara i ett lager bredvid varandra. Men i
Using pictures of patient data to predict hospitalization Predicting patient hospitalization has been a major objective of health care providers due to its impact on patients’ life quality. These benefits are demonstrated in driving down health care cost in addition to lowering mortality rates and complications due to unplanned hospitalizations. Like any other patients, dialysis patients experi
Purpose: To estimate the impact upon Health-Related Quality of Life (HRQOL) associated with Type 1 Diabetes Mellitus (T1DM), both with and without associated diabetic complications, for enabling calculation of utility values – Quality of Life Weights (QLW) – for populations with T1DM. Method: Two cohorts from Northern Sweden, one of T1DM patients and one of a general population, were given survey
The restriction modification enzyme system is a vital bacterial defense system against invading phages. Restriction modification system consists of a restriction enzyme and a methyltransferase enzyme that work in a complementary fashion to cut foreign DNA and at the same time methylates and protects host DNA. Recognition site sequence is usually specific for each restriction enzyme. Restriction Re
Bekämpningsmedel kan påverka könsfördelning hos vilda bin Neonikotinoider ingår i många av världens mest använda insektsbekämpningsmedel. Olycksbådande resultat från ett flertal vetenskapliga studier har gjort att man nu börjat ifrågasätta de effekter neonikotinoider har på nyttoinsekter som honungsbin, vilda bin, humlor samt andra harmlösa insekter. I denna studie undersöker man hur en vanlig ar
In this master thesis, the topic of energy storage connected to concentrator photovoltaic power production is assessed. The end goal is to propose the optimal energy storage technology and its sizing, regarding power and energy capacity, for an existing concentrator photovoltaic power plant. The plant is located in the province of Algarve in Portugal, the installed production capacity is 4.5 MW, a
This thesis suggests and tests two methods for categorizing instruments in a musical signal. The first method involves spectral analysis and the magnitude spectrum, analysing the structure of pitches and overtones and how the amplitude of those changes over time. The second method involves cepstrum analysis and especially the, for speech recognition popular method computing the Mel Frequency Cepst
In order to understand how the Pleistocene glacial cycles have influenced the diversification in the Reed Bunting (Emberiza schoeniclus) subspecies complex, we conducted a multilocus phylogeographic study. We analysed DNA sequences from 32 breeding populations, covering the species’ Palearctic distribution, and used population genetics, phylogenetic and coalescent methods to uncover genetic struct
This paper investigates the impact of HIV prevalence on schooling achievement. By associating data of schooling test results, for seven countries in Sub-Saharan Africa, with regional measures of HIV prevalence for 70 different regions, I find evidence that a general increase in HIV prevalence of about 1%, lowers general test score results of about 1% of a standard deviation from the mean. Endogene
